Help ! Swing Performance tuning

Hi All
what if I go on adding n number of components to the same location of a container without removing the previouly added component to the same location? the component count goes on increasing obviously but is there any performance issue when I remove the earlier one and then add the new one to it?
e.g. If my JFrame contains one center JPanel and after every 10 seconds i want to change the center panel. If i just do it by setting earlier panel to visible false and add new panel to the center won't it increase the size of component list maintained by the container? does removing earlier component add then adding new one give better results over this?
Shailesh

Shure you get better performance, when removing not-used panels. Furthermore, swing-panels are very memory-consuming.

Need help in Performance tuning for function...

Hi all,
I am using the below algorithm for calculating the Luhn Alogorithm to calculate the 15th luhn digit for an IMEI (Phone Sim Card).
But the below function is taking about 6 min for 5 million records. I had 170 million records in a table want to calculate the luhn digit for all of them which might take up to 4-5 hours.Please help me performance tuning (better way or better logic for luhn calculation) to the below function.
A wikipedia link is provided for the luhn algorithm below
Create or Replace FUNCTION AddLuhnToIMEI (LuhnPrimitive VARCHAR2)
      RETURN VARCHAR2
   AS
      Index_no     NUMBER (2) := LENGTH (LuhnPrimitive);
      Multiplier   NUMBER (1) := 2;
      Total_Sum    NUMBER (4) := 0;
      Plus         NUMBER (2);
      ReturnLuhn   VARCHAR2 (25);
   BEGIN
      WHILE Index_no >= 1
      LOOP
         Plus       := Multiplier * (TO_NUMBER (SUBSTR (LuhnPrimitive, Index_no, 1)));
         Multiplier := (3 - Multiplier);
         Total_Sum := Total_Sum + TO_NUMBER (TRUNC ( (Plus / 10))) + MOD (Plus, 10);
         Index_no   := Index_no - 1;
      END LOOP;
      ReturnLuhn := LuhnPrimitive || CASE
                                         WHEN MOD (Total_Sum, 10) = 0 THEN '0'
                                         ELSE TO_CHAR (10 - MOD (Total_Sum, 10))
                                     END;
      RETURN ReturnLuhn;
   EXCEPTION
      WHEN OTHERS
      THEN
         RETURN (LuhnPrimitive);
   END AddLuhnToIMEI;
http://en.wikipedia.org/wiki/Luhn_algorithmAny sort of help is much appreciated....
Thanks

There is a not needed to_number function in it. TRUNC will already return a number.
Also the MOD function can be avoided at some steps. Since multiplying by 2 will never be higher then 18 you can speed up the calculation with this.
create or replace
FUNCTION AddLuhnToIMEI_fast (LuhnPrimitive VARCHAR2)
      RETURN VARCHAR2
   AS
      Index_no     pls_Integer;
      Multiplier   pls_Integer := 2;
      Total_Sum    pls_Integer := 0;
      Plus         pls_Integer;
      rest         pls_integer;
      ReturnLuhn   VARCHAR2 (25);
   BEGIN
      for Index_no in reverse 1..LENGTH (LuhnPrimitive) LOOP
         Plus       := Multiplier * TO_NUMBER (SUBSTR (LuhnPrimitive, Index_no, 1));
         Multiplier := 3 - Multiplier;
         if Plus < 10 then
            Total_Sum := Total_Sum + Plus ;
         else
            Total_Sum := Total_Sum + Plus - 9;
         end if;
      END LOOP;
      rest := MOD (Total_Sum, 10);
      ReturnLuhn := LuhnPrimitive || CASE WHEN rest = 0 THEN '0' ELSE TO_CHAR (10 - rest) END;
      RETURN ReturnLuhn;
   END AddLuhnToIMEI_fast;
/My tests gave an improvement for about 40%.
The next step to try could be to use native complilation on this function. This can give an additional big boost.

Very urgent-----help in performance tuning

hai all,
I had used inner join for getting data from 5 tables.
performance is very low in this case.
now i want to increase the performance. how can i do this.
coding for the select statement is ......
SELECT agpnr bname1 bname2 bpstlz bort01 bstras b~street2
           bname1_maco bname2_maco baliasname bispadrbsnd
    INTO CORRESPONDING FIELDS OF TABLE it_tab
    FROM jgtgpnr AS a
    INNER JOIN jgtsadr AS b ON
    aadrnr = badrnr
    INNER JOIN jjtvm AS c ON
    agpnr = ckunnr
    INNER JOIN kna1 AS k ON
    agpnr = kkunnr
    INNER JOIN knvv AS v ON
    agpnr = vkunnr
    WHERE ( ajktokd = 'MADV' OR ajktokd = 'MADO' )
    AND c~vkorg = pr_vkorg
    AND v~vkorg = pr_vkorg
    AND gpnr IN so_gpnr
    AND k~aufsd IN so_block
    AND v~aufsd IN so_blck
please give me a good suggesstion for this.
thanks in advance.

Hi
Try to use for all entries
Eg
if u have itab1 and itab2.
      select vbeln netwr from vbak into table itab1.
      if not itab1[] is initial
      select vbeln matnr matkl from vbap into table itab2
      for all entries in itab1 where vbeln = itab1-vbeln.
      endif.
Hope this will help u.

Need help in Performance tuning

Hi All,
        I am facing some performance issues in my program. The program taking a hell lot of time to execute and some times timing out without giving the out put. This is a report program with ALV output. It is handling mainly Sales related data.
       The program is fetching a huge volume of data from different tables and processing this bulk data inside the loops several times. In most of the queries I am unable to supply all key fields, because my requirement is like that only. I have many places in my program i am using inner loop and function modules inside loop etc.
        Any pointers on this will be a great help.
Regards,
Jijeesh P G

1) Make sure that any READ or LOOP inside an outer LOOP accesses the inner table with an appropriate key (either using BINARY search when reading a standard table or using sorted/hashed tables for inner tables only). This helps in most cases.
2) If the tables witdh is more than aprox. 30 bytes LOOP ASSIGNING <wa> may help a bit. Declare <wa> for each table separately using the tables line type (otherway type casting would cost some additional time).
3) You may use FM SAPGUI_PROGRESS_INDICATOR in the outer loops to inform the user while he is waiting.
4) A COMMIT from time to time will reset the measured time for timeout ( and therefore avoids timeouts - do NOT use without checking step 1) ).
4) The programm may use virtual memory if a huge amount of data is selected ( I have seen dumps in due to the fact that nor more disk space was available). So - if STEPS 1)-3) failed - look a the process for rollling in/out).

Need help with Performance Tuning

Following query takes 8 secs. Any help will be appreciated
SELECT SUM(FuturesMarketVal) FuturesMarketVal
FROM (SELECT CASE WHEN null IS NULL THEN FuturesMarketVal
ELSE DECODE(FUTURES_NAME, null, FuturesMarketVal, 0)
END FuturesMarketVal
FROM (SELECT SUM( (a.FUTURES_ALLOC * (NVL(b.Futures_EOD_Price,0)/100 - NVL(c.Futures_EOD_Price,0)/100) * a.CONTRACT_SIZE) / DECODE(a.CONTRACT_SIZE,100000,1,1000000,4,3000000,12,1) ) FuturesMarketVal,
a.FUTURES_NAME
FROM cms_futures_trans a,
cms_futures_price b,
cms_futures_price c
Where c.history_date (+) = TO_DATE(fas_pas_pkg.get_weekday(to_date('12/30/2005') - 1),'mm/dd/yyyy')
and a.FUTURES_NAME = b.FUTURES_NAME (+)
AND a.trade_date < TO_DATE('12/30/2005','mm/dd/yyyy')
AND b.history_date (+) = TO_DATE('12/30/2005','mm/dd/yyyy')
AND a.FUTURES_NAME = c.FUTURES_NAME (+)
GROUP BY a.FUTURES_NAME
/

Eric:
But there are only 5 records in cms_futures_price and 10 in cms_futures_trans :-)
OP:
I'm not usre what you are trying to fo here, but a couple of comments.
Since NULL IS NULL will always be true, you don;t really need the CASE statement. as it stands, your query will always return FuturesMarketVal. If the results are correct, then you can do without the DECODE as well.
Why are you calling fas_pas_pkg.get_weekday with a constant value? Can you not just use whatever it returns as a constant instead of calling the function?
Are you sure you need all those outer joins? They almost guarantee full scans of the outer joined tables.
Perhaps if you post some representative data from the two tables and an explanation of what you are trying to accomplish someone may have a better idea.

Steps for performance Tuning....!!!!

Hi all,
I need your help in Performance tuning.
While we do tuning in Oracle, apart from Indexes, where clause and order by clause, what are the other points we need to check. I mean explain plan etc...
I am working as Informatica Developer, but i need to make an documents which points out what are the step we can check while doing performance tuning on SQL queries.

Performance tuning help

hello friends,
i am supposed to use ST05 and SE30 to do performance tuning,and also perform cost estimation,
can some plz help me understand, i am not that good at reading large paragraphs, so plz donot give me links to help.sap
thank you.

Hi
Se30 is the runtime analysis
Here it will give you detailed graph about your program .
abap time,database time application time ..
st05 is sql trace where it will give you individual select stmnts in your program
and also proper index is being used or not.
Other performance tips
check any select stmnts inside the loop and replace with read statement
use binary search in read stmnts
use proper index in where condition in select stmnt.
if you want to execute st05..go st05..trace on-execute ur program--come to st05..trace off and --list trace...
you get summary details of select queires and it will be pink or other color.
Thanks

Help request for Oracle DB Performance tuning

I need some help on Oracle performance tuning.
My environment is VB 6 frontend & Oracle 8
in backend.
The problem I am facing is particularly in
muli-user environment. Some query which takes
20 seconds to when there is only one user
working in the network, takes more time
(3 minutes to even 5 minutes) when there are
4-5 users working in the network.
What may be wrong ?
Are there any parameters that I can
fine tune ?
We checked the resource utilization at the
server level CPU utilization is max 50 %,
Memoery utilization is 50 % (250 MB out of available 512 KB)
null

Hi Vinay,
There can be many reasons for time delay.
Here are some--
1) You may not be releasing the locks on objects quickly after use.
This can be obtained by querying v$locked_object.
2) You may be holding many sessions concurrently and not closing the older ones.
This u can get by querying v$session.
These are some common problems in multi-user platform.
R u using MTS?

CF Performance Tuning Help

I moved our internal application from a P3 500mhz CPU 1U
server to a Duo-Core Xeon 1.6ghz server.
The newer box has a larger HD, more RAM, beefier CPU, yet my
application is running at the same or a smidgen faster than the old
server. Oh, I went from a Win2k, IIS 5.0 box to a Windows Server
2003 running IIS 6, mysql 5.0.
I did a Windows Performance Monitor look-see. I added all the
CF services and watched the graphs do their thing. I noticed that
after I ran query on my application, the jrun service Avg. Req Time
is pinned at 100%. Even several minutes after inactivity on the
box, this process is still at 100%. Anyone know if this is a
causing my performance woes? Anyone know what else I can look at to
increase the speed of the app (barring and serious code rebuild)?
Thanks!
chris

Anyone know what else I can look at to increase the speed of
the app
(barring and serious code rebuild)?
There are some tweaks and tips, but I will let more knowledge
folks
speak to these. But I am afraid you problem maybe a code
issue. From
the brief description I would be concerned there is some kind
of memory
leak thing happening in your code and until you track it down
and plug
it up, no amount of memory or performance tuning is going to
do you much
good.

Report running for long time & performance tuning

Hi All,
(1). WebI report is running for long time.so what are the steps i need to check for it ?
(2). Can you tell me about performance tuning in BO ?
please help me.....
Thanks
Kumar

(1). WebI report is running for long time.so what are the steps i need to check for it ?
The first step is to see if the problem lies in the query on the data source or in webi itself. Depending on the data source there are different ways to extract the query and try to run it against the database. Which source does your report uses?
(2). Can you tell me about performance tuning in BO ?
I would recommend to start by reading the administrator's guide. There is a section about how to improve performance.

Performance tuning of BPEL processes in SOA Suite 11g

Hi,
We are working with a customer for performance tuning of SOA Suite 11g, one of the areas is to tune the BPEL processes. I am new to this and started out with stress testing Hello World process using SOAPUI tool. I would like help with the below topics -
1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
2. Do we need to run stress tests for every BPEL process deployed?
2. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
Thanks in advance!
Sritama

1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
You need
pay attention to:
java heap usage vs java heap capacity
java eden usage vs java eden capacity
JDBC pool initial connections vs JDBC pool capacity connections
if you are using linux: top
if you are using aix: topas
2. Do we need to run stress tests for every BPEL process deployed?
yes, you need test each BPEL. You can use "Jmeter" tool.
Download Jmeter from here: Apache JMeter - Apache JMeter&trade;
Other tools:
jstat
jstack
jps -v
Enterprise Manager
WebLogic Console
VisualVM
JRockit Mission Control
3. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
I recommend "Oracle SOA Suite 11g Performance Tuning Cookbook" http://www.amazon.com/Oracle-Suite-Performance-Tuning-Cookbook/dp/1849688842/ref=sr_1_1?ie=UTF8&qid=1378482031&sr=8-1&keywords=oracle+soa+suite+11g+performance+tuning+cookbook

[ADF-11.1.2] Proof of view performance tuning in oracle adf

Hello,
Take an example of : http://www.gebs.ro/blog/oracle/adf-view-object-performance-tuning-analysis/
It tells me perfectly how to tune VO to achieve performance, but how to see it working ?
For example: I Set Fetch size of 25, 'in Batch of' set to 1 or 26 I see following SQL Statement in Log
[1028] SELECT Company.COMPANY_ID, Company.CREATED_DATE, Company.CREATED_BY, Company.LAST_MODIFY_DATE, Company.LAST_MODIFY_BY, Company.NAME FROM COMPANY Companyas if it is fetching all the records from table at a time no matter what's the size of Batch. If I am seeing 50 records on UI at a time, then I would expect at least 2 SELECT statement fetching 26 records by each statement if I set Batch Size to 26... OR at least 50 SELECT statement for Batch size set to '1'.
Please tell me how to see view performance tuning working ? How one can say that setting batch size = '1' is bad for performance?

Anandsagar,
why don't you just read up on http://download.oracle.com/docs/cd/E21764_01/core.1111/e10108/adf.htm#CIHHGADG
there are more factors influencing performance than just query. Btw, indexing your queries also helps to tune performance
